Ledger Blue/NanoS/NanoX Environment Setup

prepare-devenv.sh

## Install Development Environment

There are two options for setting up our environment

**Option 1**: Using Ledger Vagrant
-   Clone ledger-vagrant  
    > `git clone https://github.com/fix/ledger-vagrant`
-   Connect to the vagrant machine  
    > `vagrant ssh`
-   Move to the app  
    > `cd apps/ark-ledger`


**Option 2**: Using Python3-env.

Linux:  
-   > `sudo apt install python3-venv`

macOS:
-   > `brew install python3`
-   > `pip3 install virtualenv`

Now we prepare the Ledger device environment.
-   > `source prepare-devenv.sh x`
    > _(x or s, depending on your device)_  

> *_note: `deactivate` to exit python3-env

## Building and flashing our app
-   Connect your ledger Nano S
-   Run the script
    > `sh ./rebuild.sh` (ie. build, delete and load app on ledger)



# shellcheck disable=SC1091,SC2155

# SOURCE THIS FILE
# . prepare-devenv blue|s|x


# To prepare your dev environment
#
# sudo apt install python3-venv
#
# source prepare-devenv.sh x 
# (x or s, depending on your device)

# To build/rebuild
# sh ./rebuild.sh

# If this process gets stuck or bugs out,
# just delete the 'dev-env' folder and run this script again.

# If you get `hidapi` errors, install the following:
# apt-get install libudev-dev libusb-1.0-0-dev -y > /dev/null
